I would recommend you, have another and better layout. Since this layout is broken for mobile, same for desktop is a little mess.
Hopefully you applied some basic essentials like label for checkbox and radio buttons, placeholder for textfield and a disabled default option for combobox, very good.
Submit button is sharp and cool I like it too.
About colour scheme, the blue colour could be a little lighter so black colour is more clear as foreground,
I suggest you read my post about survey form challenge walkthrough (feedback is appreciated too). I stated some tip, template layout and suggestions there, could be helpful I hope.
Keep goin on great work, fix the layout first, it’s essential.
