There are some internet sites that will sell you pictures also. One of them is advertised on the first page of this forum (zazzle). I have never used them but you might take a look. Never worry about criticism, if you like it, someone else will also, and for those who don't like it, well, they have no taste :-)

You might try to sell your work through a local framing store. Some of them sell works by local artists. This way you don't have to interact with the people who are looking. Just collect the money when they are sold.

Jeanhdl; Haven't see it on here, but, there is a canvas printer I use called "Canvas POP". prices are great and so is the service. I will look into "Canvas on Demand" also. It's always good to have a backup. I have started sending pictures in to use as Christmas presents. I may have some printed up for sale as well as I have had some inquires for my work lately. Your pictures are terrific as are many of the others posted here.
