It looks great for a prototype. Im not much of a systems mocer however I have some tips.
Most mocer have problems with scale of their "ships". I think your moc would even look cooler if you are able to "scale it" in perspective so it won't look to simple to produce. If you know some photoshop, try it. It work wonders. Sometimes a simple moc becomes viewed more because of its presentation. trust me. As you advance in mocing ability, try advancing as well in how you present your creations in mocpages. Rate your own page and not moc as well before you finally post it. For me presentation counts 30%, originality 30%, build 30%. Main picture counts 10%. Don't stop when you have already posted. Try editing your page from time to time by correcting gramatical errors and improving pictures(the earlier the better though).
