Heres some issues that I can see right off the bat from the screenshots alone (If the screenshots are not representative of the current build then reupload new screenshots). Scaling: Unless you are going for a "new size" rocket design and are planning on making new pods etc I seriously reccomend you scale them to fit the current parts. Textures, a bit bland and have your username on them. No one wants to use something with your own name on it. No offence Features! I understand that you are making a tank expansion mod but seriously in my opinion we dont need more tanks. Add some features to them, make them unique, give them an animation or something. Something to make them stand out either as stylish tanks or useful tanks. Perhaps make them have a ladder on them or something that kerbals can climb up. Just throwing some ideas out there. In its current stage, honestly, its just a couple of cylinders with fuel content. Not trying to put you down but keep working at it, add more to it, and attempt another release say a couple of weeks down the line.
