Thank you very much, worked perfectly.

#wcvendor_profile_logo img{border-radius:50%}

.dokan-store-support-btn{width:auto !important}

you can place this in theme options - general options - custom css

1 - Could I ask if you could please supply some CSS to match the round container for store Avatar photo in store list page https://stage.mytanklife.com/store-listing/ with individual vendor page? https://stage.mytanklife.com/Store/polaris-home-aqurium/.   It look rather strange to move from round to square between pages. I noticed that some other themes using Dokan keep it round on both pages. 

2 - Can you please supply some CSS for mobile view to align "Get Support" or all menu items, to the left for proper alignment? It also look strange floating in middle.

Thank you, it would be appreciated
