Ahh I'm glad you liked it! Your art while still clearly developing has a fairly good color scheme for her complexion, dress and so on, I didn't feel the need to change any major colors, just add on to them (I feel like when someone has good ideas, they show it regardless of skill). Feel free to take reference on these drawings I made, since I usually also take references myself (the dress details were inspired by 2 different models of dresses i found online for example).
As for twitter, you can definetly post the images! I have a nsfw account and although I haven't posted anything there yet you could tag it, I'm planning on starting to post there at some point this year: @artemis_zer0
I hope your game continues developing! I kinda got attached to it now lol (if you dont mind I might continue to redraw some stuff, the model I drew is working so well in some scenes but in others it's like totally bugged lmao), its also really fun to mess around with the layers, reminds me of paperdolls and I've been meaning to get some experience with those!
