I would recommend an ipad because compared to other devices I prefer drawing directly on the surface without looking at other screens. This might be a very personal reason to buy one but I like to draw on the go, so for me it was very useful to also not forget ideas and just sketch roughly before completing the work later. If it is your first purchase wouldnt buy a big ipad I think the small version is perfectly fine for sketching and it has an ok price compared to other bigger/newer versions and it's good to take along.

For finding a personal style...I dont really know how to help other than saying looking/recreate art styles that you feel align with what you want to draw? I personally read so many mangas and have so many artbooks of artists I loved since I was like...10yo that at this point my style established itself just by absorbing all those art styles and taking apart certain features and vibes I love. So for you I would say the same I guess look at artists you admire, look at their arts, their style, the emotins the convey and try to recreate it? I dont think there is nothing wrong with trying to recreate a certain art style or pose for the sake of improving c:

if you want wholesome, the final ment of the first leg of TDS2, from chenle to mark, but especially where rj says if his life was a movie that moment would be the one he will remember forever (or something like that) and when mark says the dreamies are so cute too :cc That concert was something they wanted so much and it meant so much as a team coming back together to rewrite their story as nct dream.

if you want funny any of their cooking/grocery shopping content from markjenle not buying spring onions, to jaemin cooking lovely for jisung, to marklee fucked up eggs + markjaemle playing pubg (i think) and mark keeps saying I GATCHY while in fact he got nobody's ass

Alpha characterizations really depends on you and what you find the most attractive in someone that would define an alpha
For me It's not only mark's role as the leader in dream that makes me portray him more as an alpha, but also the way nct overall see him and respect him. I see Mark as someone wth a great sense of responsability, he is very ambitious and can be very stubborn when there is something he wants (or someone since we are talking alpha/omega). With the way there is such a codependency in dream with him that has been expressed multiple times, I just cant think of him as an omega most times. There is nothing wrong with it (i have ships where i dont mind him as a bottom, but mostly i am a top mark stan) everyone has their own characterization, but for me seeing that kind of relationship makes me think of him as someone that people would follow at the end of the world. In abo terms, this translates to an alpha and his pack.
Mark is also kind and thoughtful, he seems to look after others more than himself, which this could also apply to an omega but for me an alpha that would do everything to make his omega feel well takes care of is very sexy.
I dont consider strenght a necessary trait for alphas but I guess I will put this in too cause omegas are usually looking for safety and Marklee multiple times have showed great strenght or in general a very powerful aura around himself that I feel like it draws you in and it would make every omega gag a little
He is also stupidly funny and I feel like that's a precious trait to give to an alpha like your omega is sad and going through a messy day the least an alpha can do is to make his omega's day better

Do i need to mention hes got a really big
