It's a cool suit, but not the best idea for your first suit. Also, before making that plunge, you need to learn more about what you like and don't like, and most importantly, the proper fit... particularly the shoulders and length.
I'll tell you what I do and don't like about it, and then you can check to see if you even considered it. If not, I suggest you learn what you like before making such a purchase:
Pattern, seems interesting (but not the most versatile)
Oxxford, very nice brand
Shoulders - based on what I can see, they look well executed and my style (roped), however, it's hard to tell without trying it on
Ticket Pocket - Not a bad touch
I don't like:
Lapel width - it's too narrow for my liking, and I'd prefer peak lapel on three piece
Button stance could be a bit lower. With that, the waist seems to be a bit high as well.
Vest seems to sit quite high as well... I'm wondering if the seller used a vest from a different size/length than the suit jacket for the photo (could have multiple sizes to sell)
Have you at least thought about most of these things? If not, I suggest you figure out what stylistic features you want as well as the proper fit before considering this.
Just my 2 cents.
