Ok, rules for a good logo design:
1) It should be readable! Here, i can hardly spell out the letters!
2) It should work on many backgrounds, especially dark and white!
3) Try to print it and tell us if it's nice, then make a copy of it, and you'll see that it must be sharper.
We usually work with vectors for logos, because of its contrast.

Keep on working!

To me, the logo looks a bit plain and does not stand out much. The main part of the logo, i.e. the text 'DWA', needs to be different colour to the background in order for it to stand out. Also, you should aim to keep the image sharp and not blurry to make it look more interesting.
