Looks pretty good to me. I would just work on rounding up the lines a little more to get a better flow with things, couple kinks here and there but overall not bad. Another thing I might consider doing is lowering that cheekpiece some going up towards the comb so as to improve the flow of it, at least lean it back so the end of it points at the lower corner of the buttplate tang. Also the back end of the cheepiece stands kind of straight up and down I would lean that back a bit. I like to have the carving kind of flowing off the back of the cheekpiece personally. What you did behind the tang looks good. Good luck, Regards, TC
Also now that I look at it a little more, that squiggly that runs up to the inside corner of the buttplate, I'm not so sure that works. Not sure what I would do there. I know what you mean about things looking different after you go away and come back later. Sometimes laying something down and coming back later is a great aid in preventing your work from surpassing your judgement.
