Hey, welcome to dA! You're art's looking great. I'm sure being on dA's gonna help you make it even better.
You said you struggle trying to think what to draw? Well if you're looking for suggestions, fan art's a pretty good way to go. You get to draw from an endless pool of characters you love, plus you'll be able to catch the attention of people who love those characters too! Just a suggestion, hope it helps.
Thanks for the fav!
