Since this is 'a muslin' I won't comment on your pressing (every garment/every seam needs pressing as you sew them and not just after you're done -- hint, hint!!) I can't quite tell but I think your buttons are too close to the edge. The button holes look about right but are your buttons right at the edge?? Most of the time there is an ample overlap -- if you put the buttons there because otherwise the blouse would have been too tight then you need to add on the pattern and not take away. On this same topic -- and one of the reasons I believe the buttons are too close to the edge is that the collar looks like it may be too far apart -- but I have not seen the pattern either. Yet another modification I would make is take off maybe 1/2 inch off the top of the shoulder -- you'd have to play with how much to take off but typically this type of sleeve sits higher on the shoulder and not dropping off -- it's really, really a minor fitting adjustment. You don't have to usually even adjust the sleeve because the difference will adjust with the gathers. I would not take the blouse in - it looks like it fits very well from the picture. Moving the buttons over just might take up what feels like 'it's too big!'
Overall, it really looks well done and for the most part is a good style for you -- I'm hoping you don't take what I have said as criticism because I really had just hoped to give you some help -- good luck!
