post a screen shot of your base.
there are many strong bases that have already been designed by very experienced players. try out one of their designs and if you want, you can make adjustments to personalize what you think would work best.
try searching on youtube or google "junliang pokeball clash of clans", which is a pretty solid town hall7 base.
as you mature as a clasher, you will notice things that work, and things that dont. resulting in being competent enough to design your own bases, or using others designs to influence your own decisions on what makes a functional base.
