Nice job! Sorry for your experiences with painting the parts attached to the sprue - I guess we all had to learn that lesson 😅 I went over to drilling little holes into the parts and sticking some toothpick into them before painting the base coats but even then sometimes the toothpick breaks. Or when I try to glue them together there is paint in the way that I have to scratch away - which also has lead to some broken plastic I had to glue again. So I would recommend next time just get one mini out of the sprue, remove moldlines and glue it together before painting - perhaps you will see it's not as bad as you initially thought. I realized when the mini is properly coated with the base coat the spots you cannot reach are still ok in the overall look. In fact the observer's eyes mostly fix on the more interesting parts that are usually not in the deep recesses 😀
