My first llustration for my Article

Hi everyone! Happy to be on Dribble and happy to present my first shot :)

Specializing in UX/UI and Motion Design this is my first try of making an illustration. The illustration was made for my Article "Saving money, time and energy working with design teams".

I decided to make this illustration on the wave of impression by the works of @JulienRenvoye https://dribbble.com/JulienRenvoye

Not all of the objects on illustration are my own (office e.g.) some of them copied with minor changes from free stock illustrations and some of them are of my own authorship :)

What do you think taking into account this is my first illustration experience?

Will be grateful for your opinions, comments and appreciations. Thank you! :)
