The GW250's headlight unit is somewhat unique. If you don't like it you can change it. Here are a couple of options.
First is converting the headlight from a simple H4 bulb to a projection type with angel eyes. This is very popular in China although I have yet to find a kit. Rather it seems you have to hack up the stock unit. But it does look cool and it supposedly provides better lighting.
Some of the guys in China do these in colors. I personally don't recommend that and it is illegal in the USA and Canada and I would assume other places too.
If you want a more traditional look why not mount a headlight from some other bike. Here is a photochop with the headlight from a JDM Honda CB400.
I really like the look of the angel eye, quite sci-fi. Still not sure how I feel about the CB400 photochop. I mean the GW250 is styled angular and modern, the round halogen just seems to set the design backwards...
I think that the traditional round headlight doesn't suit the GW250 very well. The first option looks cool though. I don't have a huge problem with what the stock headlight looks like but I would consider the first mod.
The round headlight is traditional but the GW250 is anything but that. Its design is distinctly modern so I just don't think it looks right. It might look better if mods were done to other parts of the bike as well. For starters I would change the mirrors. Maybe a round headlight that had a projector in it would look better too.
