Nice little gallery

Practice. You're getting it, but practice. ALOT.

Ur pics. really S**k.

you are off to a wonderful start and you have tons of talent, but, yes theres alway a but, but first get a scetch book No more line paper (I know its handy) but quality paper is inspiring on its own. Secound dont be afraid of color but alot down. we want to see the color. Third if you are really serious about your art theres a book out called drawing from the right side of the brain. Its easy to find. If you get the book and do the lessons in the book. You will see your art inprove 100%. I did and was amamsed in the changes in my art. Well I hop all this helps you. By the way this is fantasy art, the means drawings from you imaganation so that means nothing is wrong if its the way you see it in you minds eye. sorry about my spelling hope you managed trew it . Keep up the good work
