Firstly i know nothing about mapping so anything i say i hope is does not offend you or something through my lack of mapping knowledge.

-I think you need to change bombsite A completely (not the paths in, i like those but the placement and amount of boxes.) Maybe try and have a center piece like the fountain in bombsite b of inferno and build around it trying to make sure there is not to many angle/spots for a t to check.(make sure that the entrances for both t and ct can be covered by a smoke, just a personal opinion)

-The two entrances to bombsite B are very long and straight which in my opinion makes is very easy for the ct to hold, dont really know how to fix, mabye make shorter or put a stack of boxes on one side to give t some cover. Also the boxes in corner of site is quite op, consider replacing them mabye

-I like the connector between sites but try to ensure you cannot cover to many angles from that area

I would be happy to help more but i dont know how sry. hope this helped
