Very nice design Emran. Thanks for sharing with us.
I agree with both Biju and Shad.
Want to add few things -
1. Your nicely illustrated banner is a good start for the page but later there is no trace of any illustration.
2. For categories, you can use icons instead of images. images are not working here. Also if you use icons, it will be consistent and can make a connection to the illustrated banner. You already have those icons illustrated.
3. In popular searches, it seems there are too many popular items. You can drop one row. Then it will be more meaningful.
4. Sell anything on Smartarz - You can make this section more interesting. black mobile can be blue ... need to consistent with your top banner.
5. Footer can be interesting than this.
overall you can see too much white and monotonous. Using green background for some sections can break this monotonousness.
I also want to see the mobile version of this ( if you have)
