Concept Art

I have always loved concept art of all type, you can get so much out of so little. Here are my first attempts.
The first was done in painter mostly and was based off a crappy phone camera shot i took one cloudy day.
The second was a tutorial i saw on deviant art, i followed it but modified the (desert/broken spaceship) for a (ocean/submarine) theme instead. The last was drawn over a female krump dancer off google images which i modified to be male and did the rest free hand to express the motion of aggressive dancing.
