Wow... he's certainly looking quite big... his topline is looking better, but like others have said still has a wee way to go!
Good luck over winter! I know how hard it is to keep weight on some horses, my gelding in particular is still very light (he has a teeth issue, can't get low grass, so no matter what I fed him over winter he stayed incredibly light)... I too like to go into winter with a bit of weight on my horses, but you said you didn't want any opinions on his current weight, so i won't say my opinion about it.
