Hi @ogochukwu
Here is my opinion about the unDraw
Pros:

• Provides an open field to all the content creators to put the desired images
• Updated collection of svg images provided without any cost
• Pixels remains constant of the images
• Page loads quite frequently and easily as the sizeof the file is small
• Edit option is always available to adopt the desired color
• Quite easy and pleasant to use

Cons:

• None found for it

Over all a wonderful Hunt, keep hunting :)
