requiem for a dream

i guess this is fan art. i did this a while back. decided i wanted some feedback because i want to draw more but need some contructive criticism. i fixed up his bottom hand a little cause it is a little funky here.. so yep. i gave this to my friend cause he loves this photo and when i drew it he liked it so i figured why not. yepyep.

heres a link to the original image- im not sure about copyrighting stuff but its copyrighted to who ever made the movie...?
