Some comments if I may.
First, Hitech released old skins with the lot of new planes. They haven't had the chance to update the skin. So basically you're stretching a 216x216 pixel out to 1048x1048 (roughly). Hence you can see a lot of the pixels.
I'd either wait until they release the new high graphics skin, or work on cleaning up the old skin to be ready for 1048x1048.
Next, the checkerboarding on the nose goes too far. You need to cut back on 2 of the lines. From counting on the website you gave, the checkboarding (if considered horizontally) goes white black white black white black. So 6 squares.
Lastly, increase the opacity of the checkerboarding. It really really looks washed out.
