While the paintjob is fine, there doesn't appear to be any conversion done as its still very much a Blood Angel, just painted blue.
I can see the Blood Drops on the chest armour, the hammer, the storm bolter, dangling from the belt, on left leg and on right leg.
Usually, and I don't want to sound demeaning, a conversion involves changing the model so it fits its new home.This also inclused removing all old iconography that doesn't fit with the new theme.
I'd say you got the painting down fine for tabletop already, just maybe up your exacto blade game
