I know you are early in development but let me give you some texturing tips.
If you notice on round objects like water tower or what ever it is you made, the textures are not aligned.
There is a VERY easy way to fix it!
First open your texture window (this will stay open the whole time).

Take a look at this picture. If you notice, the textures are not perfectly aligned.

First select a face that you want to be the reference.

Now Alt-Right Click the next face.

And Viola, they are perfectly aligned.

You see those grey textures, doing this trick can help you quickly change textures

.
BTW: I just found out about this tip 2 weeks ago. I wish I knew about this while making rocket city >.<
