i dont have a witty drawing for this one but im happy to answer best i can

first of all, thank you man, thats mighty high praise! bluth was very inspiring to me as a kid for sure (specifically nimh and all dogs), so i do imagine it can be felt in my art in some way

i technically went to art school but also not. i went from graphic design, which involves very little drawing in the way you see my art now, though i think it helped me think more graphically which has been good. i took some figure drawing classes but i wont say those 'taught' me anything. mostly it just forced me to do a bunch of gestures and timed studies, which you can absolutely do from home with discipline. its very good for you and i recommend it

as far as tips on finding a style and making things less stiff? the answer is boring but you draw a lot. draw so much.

theres this place where i can get thats best described as "pushing lines around" where i dont feel confident in what im sketching and im doing a lot of searching on the page and trying to jump into fine detail too quickly. im typically erasing a lot and overworking things. this is where my art is the stiffest and usually what i call my 'bad drawing days'

stiffness is frequently a lack of confidence in something, whether it be line quality, anatomy, pose, observation, etc. doing gestures or really fast observational sketches is usually how i shake off the stiffness but theres definitely a baseline that rises over time.

something i really, really recommend is drawing in pen more, and learning to work quickly and move on. do them a whole lot and i promise that act alone will yield results. i dont by any means draw in pen all the time, but i do find myself continuing to draw as if im drawing in pen even digitally, and i like what it does for me. its definitely a lasting exercise

my style has fluctuated and evolved so much over the years. i think its stabilized a bit but i expect its still evolving. try a bunch of stuff, keep what works and throw out what doesnt. theres so many little style quirks ive tried, you can definitely see various 'eras' in my art. my best advice for developing an artistic voice is being as self indulgent and obsessed in your art as possible. studies are good for developing structure but drawing what you really want to draw unapologetically is also so important. that passion will carry you a long ways and down paths you never expect. pro tip do studies but make them your ocs

arts so individual though, what works for me may mean nothing to you. half the battle is just learning what really works and prompts results. you got me yapping, thats for sure
