I feel that is fair pricing honestly..

i've only read 2 pieces of good advice:

1: paw through all your favorite artists and do exactly what they do.

2: how long does each piece take you to finish? shouldn't you be getting at least minimum wage for your work?

In terms of your pricing, that's based on where you are for what you produce along with the demand for your work.

At the moment, your pricing is fair and balanced as it's roughly equal to what many other FA users charge.

As your work improves you'll get more detailed, thus spending more time, and you'll get more notoriety, thus increasing demand...that's when your pricing needs to increase to give you a more fair "wage" for the time you spend.

Jay Naylor has been producing web comics for over 10 years and you can see a very visible change up in his work from the first one to the last one. He produces 2 comic pages a week and gives free access for people to read those comics....this is known as a "loss leader". Basically, it takes him time and effort to produce these comic pages but he gets no money in return for people reading them. Why does he do it? The main reason is that it get him noticed...it increases the public's awareness of him because:
1. Person reads comic.
2. Person tells friends about comic, friends start at step 1.
3. Person looks into other things artist does.
4. Person starts to use "pay for access".
5. Person decides to commission artist for personal work.

In terms of 3, Jay has a DeviantArt account, Furaffinity and Tumblr...and probably more that I'm not aware of. In terms of 4, he produces an adult comic every couple of months. It's usually about 8 pages long and is in full colour. He doesn't charge much for access to read this comic but he does give a "full access pass" which gives users a month's worth of access to all his adult comics rather than just the one.

5....well, he can charge a fortune for his commission work because the demand is always very high, due to the number of people who follow him and love his work. Recently, he's started doing YCH auctions. Sketching up a rough pose for a scene (usually sexy in some way) and then letting people start bidding on a thread on here. I've seen these consistently go for over $400!!!

But...the important thing to remember is that he's still producing these comics and has been for a very very long time. It gives people a reason to keep looking back on him (every Monday and Friday) and reminds users of his presence as well as drawing their attention to his extra stuff (advert for adult comics on the side of his page and links to Tumblr etc).

You've been trying to do this for a long time and have just started to really get somewhere but you also need to remember that in, terms of the build up and where you're at for making money, you're still in the infancy stage of the business. It'll take you time to get to where he is but you're more than capable of doing it...if you stick in and keep pushing yourself to improve.

I'm not saying you should start doing a comic twice a week but it would be worth you producing something on a regular basis and throwing it out there through a few different sources to reach a wider audience.

One you have demand...you can increase the cost on supply.
