Great start; only a few years ago a newbie would have given his left arm for a first image like that.
Pretty good focus, but as is to be expected with a first image, there is
significant star trailing, indicating that your polar alignment, whilst being
quite good, wasn't good enough for the length of subs that you used.
You may find that the trailing differs a bit from one frame to the next;
if so, omitting the worst frames will improve the trailing in the final image.
