Yes, it looks like you have been dabbing your varnish on to possible a previous coat which may still have been tacky, not fully dried.
Dab on a coat of varnish, leave for at least 6 hours to fully harden, this will give you an excellent base (prime) for your over coats.
Put plenty varnish (don't go crazy) on the needle and run it down the back of the fly (top) then with clean excess off the needle and use the tip of the needle to gently spread the varnish (it will already be spreading over the sides down towards the underside) but don't touch the body at all, just using the fine tip of the needle to spread the varnish.
Wait until DRY and turn fly upside down, repeat the process with a little less varnish this time. YOu will then get the smooth glassed-over appearance you are looking for.
Apart from that, the fish won't mind. Your flies will catch fish.
