I'm gonna keep dumping my stuff here - atm I will only upload some of my paintings(it ain't concept art but still), got alot of unfinished sketches out there I could upload some of them but I'd rather wait for the whole batch(to save myself some time).

Update: 29/04/2011 - Here are some of my older works.
One of the very first pieces I've made using a tablet - Autodesk Sketchbook/Photoshop, around 2 hrs of work this was made January 2010
War Mech Concept
I made this one around the beggining of 2010, it's kind of messy at some points, well to be precise all of my works back then were kinda messy, i was more of an impatient guy back then, correcting such a thing is a precise work(if you don't want to erase any details by accident)
Well this one is very messy xD, but it's mainly cause of the effort i put into making it, just a quick draft no more than 30 minutes of work.
That's the last piece I've finished in photoshop, it was made around summer holidays last year i haven't touched the tablet since then :<.
This was made around the end of the summer 2010, I've decided then to clean up my style abit, you can notice a more clear outline rather than shitfuck of random lines.
That one took me 15 hours to finish - that's the longest time i spend on a single piece of art, it was spread throughout 3 months or so, finished it around may 2010, entirely made with a 0.5 mm automatic pen :D.
