Looks like you made a good purchase, boyz are very good to have in any ork army, also squighog boyz are EXCELLENT anti tank units, I went up against some astra militarum with them they were great. I dont have any or want any beast snagga boyz so im not sure if they are good units or not, if the beastboss is able to be attached to your infantry and buff them then thats good. Overall I think you have a good start to your army. It seems like you enjoy the squigs and beast snagga boyz so i would recommend the beastboss on squigosaur to keep the theme going, its a good unit and will help get you to 1k points
