wow if thats your first your REALLY GOOD!, only thing I really see wrong is that need to just blend the render in more with the bg, just like get a brush and lower the opacity and brush along some of the edges of the render, also ttry and pick renders with a better quality it will make your art look so much better, but over all this is sick for a first one better than everything ratchet has done :-D

Thanks for that pal :D
I've seen some of Ratchets work and i can safely say im not that good... yet :P

Well done if its a first sig bu the render is far too dark and needs blended also the brushes sort of stop at the bottom right and left of the render but yea well done
