Regarding commissions

So this has been something that's been on my mind for a while.

All of my commissions so far have been from DeviantArt, partly because I didn't advertise much on other sites (which in turn was because my PayPal didn't work properly), and partly because they were so cheap that many of the site's users could afford it.
But they went as low as as sixty points for a bust sketch, which is approximately sixty cents.

I am not blaming any of those who have commissioned me thus far since the prices were of my own decision, but take the example of the bust sketch.
It can take up to an hour or two to finish one, and the hourly minimum wage in either America or Korea is at least several dollars.
I am not saying that drawing is harder than working at McDonald's, but I am still taking time and effort for just sixty cents.
Which cannot be converted into money and is pretty much useless outside of DeviantArt.

In short - and this is what other artists have been telling me as well - I think I need to stop underpricing myself.

I have my PayPal sorted out now.
I want to raise my prices, advertise on other sites, and earn real money so that I can do more things such as commission other artists on other websites, and maybe even save up for the future.
This is not saying I would be closing points commissions completely; I may still do simple commissions at a relatively low price, and I plan to take requests from time to time.

No, I don't think my art's good enough to be super expensive.
I'll be mostly basing my new prices around half of the minimum hourly wage; since that of S. Korea is about $7, I am considering somewhere between $3~7 as the starting price for a bust sketch with no color.

What do you think?

P.S. I'll also be getting rid of the grayscale colored sketch category. I found that it takes a similar amount of time to just do a colored drawing.

P.P.S. The changes won't take effect immediately; the two commissions I am currently working on will require no extra payment, and if you want to commission me right now, you can still do so with the prices (in points) listed in my Commission Journal.
