Saquib welocme back. I have lot of comments regarding this design,

shall I start? ok :
General question: Is there any special reason to choose violet color? Probably taken from logo. ok
Mark 1: Banner is so empty.
Mark 2: Don't use the light at corner for this.
Mark 3: chole, but change korte parle bhalo
Mark 4: Cool
Mark 5: Nice. Also try with Black(less opacity)
Mark 6: very nice.
Mark 7: Green Color looks Alien here
Mark 8: you have to play more with it
Mark 9: Nice but need better place. If this box is used frequently by faculties/students/staffs then definitely it should be in upper part of the site
Overall:
-Too much violet and darkish. feels heavy.
-Some places you used rounded corner and some places hard. Round looks fine to me
-Maintain the box gapes
Saquib these are just my opinions. Tumi amake ei design ta dile hoyto ei try gula kortam, tai bollam. Now its up to you
Thanks
