Hi Anna,
I made a little research for the following item in your shop as example:
https://www.etsy.com/listing/465202883/nursery-room-decoration-bird-house?ref=shop_home_active_1I think that in general you could enhance the pictures and add a little contrast to them. There are many online editing sites where you can do this for free, and there are many photo editors in Etsy who could do it for a low price. Otherwise, They are good shots and I like your items very much.
I can advice you in relation to your SEO (how you appear in Etsy search)
I think my technique to do it will help you if you decide to give it a try.
It is very important for new shops to be optimized for keywords that are often used in the USA, UK, Germany, Canada. This is because if you optimize for keywords that are used in Pakistan for example, it is very likely to get high traffic and few or none sales.
For example:
You have optimized the above mentioned listing to appear on the first page for the "Nursery room decoration"- which is a phrase with very low search index.
You've optimize for "baby room decoreation" which have very high search index for Pacistan and none for the USA, or anywhere else.
Instead you could optimize for "nursery room ideas" which have the highest search volume in the USA.
I use googletrends.com to see what is worthy to optimize and what not.
Also in the beginning of the "Shop life" it's rear to beat 1 million competition. If you search the phrase you want to optimize for in the Etsy search you will see what the competition is for these words, right under the search box.
I know that my shop can beat a competition of 17000 sometimes, you should try yours. Also when your sales increase you will be able to beat higher competition and you could change some keywords in order to get more traffic.
I hope This would help you. If you want to contact me, do so :) I will be happy to help with what I can.
Wish you best!
Iren
