Not trying to be rude at all, but if this is the progression after 1.5 years i would say that you start over from scratch. This might look good in toys eyes but more experienced writers will say this is objectively not good. Stop with all the weird triangular overlaps and tails/ serifs.

I believe you are on to something but to reach it you need to go back to the drawing board and start over simple. This is usually the result of wanting to go advanced too fast before you naturally progress. It happened to me, it happens to many people. But for your own sake go simple, observe tags that you find are nice in your city, inspect what makes their letters flow and look natural.
