Looks good MickyAs long as it vapes, it's a successful mod! I've always been a 'function over fashion' kinda guy anyway.
As for the needle depth... It looks about right to me. I have made a few of these now and I still always think it's sticking out too far when I take off the atty. But I've never had any issues.
I would say as long as it vapes and doesn't leak but, mine doesn't do that either provided you get the bottle tight enough. Given my skills I have to go for function over form I'm afraid.
One thing that surprised me is that I thought I'd have to be careful not to flood it but, it's actually pretty hard to flood. About the only time I do is when the battery's getting weak.
