Definitely invest in a tablet. Digital art changes the game.
Between your two drawings, I see many improvements. Next step is to practice drawing from mundane life. You seem like a budding character artist, so let me suggest pinup gurls, but mind what posture says. The whole “helpless damsel” or human “sex object” are really getting the axe these days, so try to say sexy, functional, independent with posture. The fighting fuck-toy with a bad attitude, a good place to start. And before you bastardize women with animals too much, try to understand both human and animal anatomy as best you can. That being said, feel free to ignore me, and draw exactly what compels you.
Stay fresh.
