Good job shanu! I love the new creative and artistic approach,

Suggestions:

I'm not good with colores pencils, so I have not much to say, but you can look for tuttorials on youtube to improve your skills.

I prefer using markers, the best are alcohol based, they blend so nicely, but they are super expensive. I use water based markers from the brand Crayola and they work very well and look very pretty and they are not expensive, also by adding a little bit of water they can work as watercolors.

Practice makes perfect, so practice making sketches of curves and different shapes and don't be scared of making mistakes, because we learn from them.

Good luck! I can't wait to see your own designs!
