Receiving a similar question in a period where I can't draw is PAINFUL XDDD
Lately I'm drawing sooo little...
I admit I enjoy making drawings of ships/characters I enjoy, but I also enjoy making drawings where I can have a lot of fun regarding the colours, the shadows, where I can put sparkles and stuff... I admit lately I'm enjoy a lot experiment with not-TD related stuff, but I would like to return to make TD drawings! I mean, technically I'm working on my newest OC ref and I'm using TD style for it, but I want to make a new TD style drawing with not stating poses, I want to try drawing Fialec!!!
Also I REALLY want to draw lolisho content, maybe using more styles other then the TD ones, but first I have some schedules: Sambukè's ref, the drawings I promised to my bf and then I hope Fialec at least...

Regarding my fav colours, I use mostly bright colors in my drawings. I especially enjoy using red because it is my fav color, I think it's evident, but I don't have particular palettes for my fanarts. I just use the colors of the characters, even if I like using effects to make the drawings brighter or more sparkling in certain occasions ^^
It really depends, maybe I should experiment more with colors and different palettes...
