A contest build. Is this for an online photo-contest or a real life judged on a table top contest?
If it is the latter, then one piece of advice I will offer, is to check out the first picture. See the round ejector pin marks? Getting rid of those is model building 101. The basics. If a judge sees those, your model might as well not be on the table, no matter how good it looks. The same goes for flash, mold lines, sprue tabs, etc.\
I look forward to seeing more. BTW, what kit is this?
