I luv your artwork, AmP! Your images look absolutely pro to me, already, but if you're unpublished (hard to believe) ... Have you checked out this pretty great (international / amateur) Sci-Fi and Fantasy Art contest:
http://www.writersofthefuture.com/contest ??? You've got what it takes to win it! Quarterly prizes are $500, annual prize is $5000 (plus a week of all-expenses-paid workshops with Big Name artists & illustrators in L.A.) Seriously ... you could win it! (I won and am going out this May ... and I'd dread competing with amazing art like YOURS) !!!

Thanks for the comment.Great port so far;)
