Did I build this wheel wrong?

If you take a look at the picture, you will notice something interesting. If I have 2 parrelel spokes on different sides of the hub, they both connect the same way. I noticed on my other wheels that they connect on opposite sites. Could this cause structural problems? I'd hate to have to redo it because it took me about 5 hours to figure out (my first wheel build), but if I have to, I will. The wheel has not been tensioned yet.

For the sake of mirror symetry it would be nice if they were opposed rather than the way they are but if the tensions are good and you don't mention it to anyone (oh yeah this is on the internet now so I guess it's too late to suggest not mentioning it at this point..... ) then no one will notice.

If I take a look at the picture, I see a very large image with your wheel in the upper left corner and a large border of white to the right and below the wheel image. This causes readers to have to widened their browser window and/or scroll bar to the right to read the text.

How's about cropping the unnecessary white area out of the image before posting next time. Thanks.

I don't know vector stress whatever, that's what I failed in college. But with tension a wheel's a wheel and the spokes look normal otherwise. Unless you're doing some crazy things on the wheel I'd leave it and say you did it on purpose (if anyone notices). Then let people drive themselves crazy trying to replicate 'that new spoke pattern that one bike has'.

If you want to build wheels regularly I'd take this as a sign that I need practice. I'd undo the wheel and start again. This is how I learned, the hard way, of all the mistakes that I try not to make anymore.

Although not a definitive "primer" on how to build a wheel, there are a few basic elements you can take and apply to your wheel building steps:

You have an asymetrically laced wheel.

There are thousands of those on the road. It's even possible that the majority of bicycle wheels may be laced asymmetrically because it's easier for machines to do. Years ago I had the opportunity to talk with an interesting fellow who was a bicycle wheel builder (At the time he also held the Guiness record for fastest flat tire repair). He told me that he was taught to lace bicycle wheels asymetrically by his grandfather. He was willing to guarantee his wheels for the lifespan of the rim's brakeing surface.

Bottom line - worry not. If your wheel fails it won't be due to the laceing pattern.

Sheldon basically shrugs it off, if I recall. He says if it doesn't bother you aesthetically and it didn't get in the way of building it, it causes no damage, so you can be happy with it.

Is that a flip flop hub? If so, claim you wanted the drive-side trailing spokes for both sides to be on the inside for maximum stiffness. It's pure BS, but if you say it with enough conviction, most people will believe you

it is a flip flop, hence both sides are the drive side, lol!

Well then, there's your "reason". You're welcome.
