Now there is a new section in the menu drop down called 'Digital Art', in the work column. You may also be able to find this work in the Digital Art Section.
After battling around 10 hours with my wacom tablet and MacBook Pro, I was able to finish my first concept art piece which is purely my original Idea.
The theme of this piece is, as you already have noticed, futuristic city. I really love the concept of Future as it allows almost unlimited imagination to be presented on the canvas.
Overall quality of the work is very satisfying except that it seems to much over to top due to all the crazy lights on the final image. Plus I think more work could be done of the left had closed up area, perhaps making it more realistic using variety of textures. However, generally I am very satisfied with the work and hope to work on more projects like this.
