Looks good, especially being your first build.
I have built over 50 points and if you don't mind I have a couple of observations.
First is the alignment through the frog, this may well be due to camera angle, but it looks like the left rail of the right track does not line up exactly through the frog. I have drawn a red line to show what I mean.
It is important that the rails are straight each way on the frog.
Secondly, are you using gauges to set your check rail gaps, they look too big to me, which gives the over large gap in the frog, which will cause wheels to drop in, especially with small GN15 four wheel stock.
If you look at this picture you will see what I mean, the track is dual gauge 16.5/32mm.
Tie-bar wise, you ideally need the fibre ones with brass rivets that pivot, which is what I have used in the point above.
Keep up the good work, it gets easier the more you do
