HC man, I think your tank looks great, keep up the good work and remember to improve with every build.
Don't worry about the comments of others, a lot of us are older and forget that being a kid is not as easy as we remember. We can't just jump in our car and run to the local HS or surf the internet and plop out our credit card to place an order. We also forget that $8.00 is in-fact a lot when your a kid. Nice effort all around.
To answer your question no B-O-T-B is not the best refrence source, but it can get your creative juices flowing. Use your imagination, you have plenty of time to work on the technical aspects of the hobby, remember to have fun, that's the most important thing.
