New at selling 3d stock, introduction myself and would like advise about models by more experienced sellers.

Your models look good. I don't see a problem offhand. You only just uploaded most of these in January of this year, so that's only like 2 months ago. You need to give it time and you need to establish yourself before you can expect to make many sales. The truth is, marketplaces like this one are really huge, and unless you are a very well established artist with a large portfolio of quality models, you aren't going to see sales happen as often as you might hope. You only have 13 models currently in your store. While the models are very good, you're going to need more than double that amount before you can expect regular sales, and even then you will need to keep adding new models often to keep the momentum going so to speak. You should choose a niche where you feel comfortable and model mostly for that genre, building your portfolio. I would recommend avoiding oversaturated categories and try to find something unique and interesting, but also something you think might be popular.

Realistically speaking, don't expect immediate results. A product you upload today may not begin to generate sales for you until months later. Maybe not even until next year! It really all depends on how much in demand that type of product is. As a new creator, you should focus your efforts on making new products as often as you can and uploading at least once a week but don't expect anything to sell immediately.

Pricing is all up to you, but one of the biggest mistakes anyone can make is underpricing their work with the expectation of selling more in volume. That's not quite how things work here. Maybe that would work in other amateur or hobbyist markets, but most people who purchase here are working for studios or on their own projects with deadlines and they will pay for what they need when they need it. Yes, overpriced items can cause you to lose a sale, but underpricing will almost certainly lose you money as well.

Really nice models you make! I startet uploading models here in november last year and haven't sold anything neither yet. Just enjoy modelling, rigging, experimenting what is possible. Am sure main problem is the vast amount of models which are on here so new ones aren't seen unless someone searches for them specifically and uses same software as you (if there is use of functions e.g. in a rigged prop / figure not available in other programs).

Mineral3D mentions another interesting thing. It has a lot to do with the software. Currently, most studios and CG professionals are still using Autodesk products for the most part. So content for Maya, 3dsmax and to some extent Zbrush make up the majority of sales here. Blender is just starting to make waves in the industry, but most of the users are still amateur and hobbyist level (not always, but many of them). So if you're selling only Blender models, you may not see quite as many sales here as you would for Maya or 3dsmax file formats. That could change in time, but Blender users get most of their content from other users for free or from Blender's own marketplace. I'm sure there are people looking for Blender models here, but not nearly as often as the other software packages.
