First, few people have a "perfect" first model but no, it doesn't suck...
You got a good basic asymmetrical shape (not a big fan of that style but no big), but I would lower the guns you got on that wing a little (IMHO they look to near the top of that section, aim for the middle would look more balanced.
After that you get a basic UV-map done for it and then convert and do table data and you're done!
later on as your skill improves you can go back and refine different parts of it and make them more detailed (higher poly or just more definition like rounded or non-thick edges). Or later better res textures.
