First of all, did you INTEND to build 1:1 scale, or just a scaled down replica. That is a big factor in judging your rocket. Secondly, are you able to configure it so you don't need the no heat cheat? If not, then it's fine, this being a replica. The scale judgement depends on how you answer my first question.
From what I see though, either way you just went on a engine and tank adding spree trying to get it into orbit. Remove ALL double tanks, and ALL engines, then start adding engines again until you have a TWR of 1.3 to 1.5 max. Then you'll easily reach orbit. And your ro ket won't weigh 4000t.
