That's nice work and it looks like you've been able to do it at low cost, also. Well done!
A minor suggestion: your rear brake cable housing looks too long (between the frame's cable stop and the brake arm). It looks like it loops pretty far down and then up vertically into a noodle that points straight down. This cable housing length is usually such that the noodle can point forwards and there's just enough cable for movement during braking action...but it stays mostly parallel to the top tube.
Again, great work! You definitely scored well on purchasing the bike and the parts.
