Really nice work, and very reasonable pricing. I’m sure that loads of people will be contacting you as your work is a great price. The GFX looks like it would really suit and work well in front page environments. Great portfolio.
The second graphic is my favorite, overall pretty good. Now my only suggestion would be take a look at the face, you can see the pixelation so I’d take it into something like Photoshop and use a combination of layers, say duplicate the image and put it behind the original and blur it and etc… and possibly doing this also for the clothes. This should help clean it all up, but for this price you’re doing an incredible job.
Lukacors is an awesome graphics designer. He made a really great thumbnail for my game, City of Boston, that really pops and brings the place together. I would absolutely recommend him for a great looking thumbnail for a good and affordable price!
