another great start, proportions are a bit off (mine are often too) it's very hard to get proportions.. Anatomy books always help. Sometimes it's good to just go with what looks good, but it never hurts to look into one either. You do excellent guys though... Much better than I've ever done, but your girls need some tweaking. Not being snobby, you have an excellent talent.. Especially considering you are only 20 years of age, you will go very far artistically, I wish you the best of luck!!
Scorpion and Sub Zero were awesome.. same character played both of them lol. I loved playing MK on sega as a pre teen, but the newer versions are a lot better. I especially enjoyed the one (Armagedon I believe?) where you could play chess!
Sonya Blade was my favorite of the original characters. I should draw her now! Ever played Soul Calibur? Much like MK, but a little more flashy!
